This design functions like modular cat apartment blocks, allowing you to reconfigure the castle layout whenever your cat needs a new challenge. Cutting offset portals between adjoining box walls creates a maze of tunnels, sleeping nooks, and elevated perches. The natural cardboard finish can be accented with colorful cat-safe paper trims.
Step-by-Step DIY Assembly
- Gather Uniform Boxes: Collect 6 to 9 heavy-duty cubic cardboard boxes of identical dimensions.
- Cut Offset Transit Portals: Cut 8-inch diameter circular holes on alternating top, side, and floor faces of each cube to form a continuous climbing maze.
- Reinforce Connecting Walls: Join cubes together using heavy-duty plastic bolt-and-nut fasteners or non-toxic hot glue applied along full contact faces.
- Create Roof Deck Perches: Leave the top surfaces of the highest cubes open as recessed perches lined with washable fleece cat cushions.
